    Exposure of Sensitive Information Through Environmental Variables

    org.keycloak:keycloak-common is an Open Source Identity and Access Management For Modern Applications and Services.

    Affected versions of this package are vulnerable to Exposure of Sensitive Information Through Environmental Variables through user-configurable URLs.

    Exploiting this vulnerability is possible with the configuration of backchannel logout URLs or admin URLs, when including placeholders like ${env.VARNAME} or ${PROPNAME}, which are replaced with actual values during URL processing. An attacker can access sensitive server environment variables and system properties.

    How to fix Exposure of Sensitive Information Through Environmental Variables?

    Upgrade org.keycloak:keycloak-common to version 26.0.8 or higher.

    HTTP Request Smuggling

    org.keycloak:keycloak-common is an Open Source Identity and Access Management For Modern Applications and Services.

    Affected versions of this package are vulnerable to HTTP Request Smuggling due to improper handling of proxy headers resulting in costly DNS resolution operations. An attacker could tie up IO threads and potentially cause a denial of service by exploiting these operations.

    Notes:

    1. This is only exploitable if the attacker has access to send requests to a Keycloak instance that is configured to accept proxy headers, specifically when reverse proxies do not overwrite incoming headers, and Keycloak is configured to trust these headers.

    2. For versions 26.x, this is only exploitable if the realm must have SslRequired=EXTERNAL (the default), HTTP must be enabled, the instance must not be using a full hostname URL, access must come from behind a proxy (assuming the proxy overwrites the X-Forwarded-For header), and trusted proxies must not be set or must incorrectly trust the client from which the request is originating.

    How to fix HTTP Request Smuggling?

    Upgrade org.keycloak:keycloak-common to version 26.0.6 or higher.

    Path Traversal

    org.keycloak:keycloak-common is an Open Source Identity and Access Management For Modern Applications and Services.

    Affected versions of this package are vulnerable to Path Traversal due to improper URL validation in the redirection process. An attacker can construct a malicious request to bypass validation and access other URLs and potentially sensitive information within the domain.

    Note: This flaw is particularly concerning for any client that utilizes a wildcard in the Valid Redirect URIs field.

    How to fix Path Traversal?

    Upgrade org.keycloak:keycloak-common to version 24.0.3 or higher.
